Thanks for that information.

I have occasionally seen cyclamen bulbs with fairly large pits,
so I think that they can recover from incipient general rot
(sometimes, perhaps rarely). And the mechanism could well be
the same. The cultivated C. persicum seem to be a bit demanding
on humidity and watering, but C. coum and hederifolium seem to
be resistant to fairly extreme drying out.
